PCA9515: I2C总线转发器
PCA9515是一款BiCMOS集成电路，主要用于I²C总线和SMBus系统应用。
在保留I²C总线系统所有工作模式和功能的同时，它允许通过缓冲数据(SDAn)和时钟(SCLn)线路以允许扩展I²C总线，从而可使用两条400 pF的总线。
400 pF的I²C总线电容极限会限制器件数和总线长度。使用PCA9515能使系统设计师将总线隔离成两半，因此能有更多的器件或更长的长度。它还可用于运行两条总线，一条为5 V而另一条为3.3 V或400 kHz和100 kHz总线，当另一条总线需要400 kHz操作时会隔离100 kHz总线。
无法串联两个或多个PCA9515。PCA9515的设计不允许此配置。由于没有方向引脚，所以使用稍有不同的“合法”低电压以避免输入和输出之间的锁定状况。PCA9515的输入上施加的“常规低电平”会以稍高的“缓冲低电平”值进行传输。当此“缓冲低电平”应用至串联的另一PCA9515、PCA9516A或PCA9518A时，第二个PCA9515、PCA9516A或PCA9518A不会将其识别为“常规低电平”且不会再次将其作为“缓冲低电平”传输。PCA9510A/9511A/9513A/9514A和PCA9512A无法与PCA9515、PCA9516A或PCA9518A串联使用，但可与其自身串联使用，因为其使用切换而非静态偏移以避免锁定状况。
当VCC= 0 V时，PCA9515的SCLn/SDAn Ci约为200 pF，相比正常值 < 10 pF。在能保证转发器电源但任一组SCLn/SDAn引脚仍保持在有效总线上的应用中，应使用更新的PCA9515A以防总线负载增加。另外，PCA9515A具有2.3 V至3.6 V的更大电压范围且可用于更低电压电源限制的应用中。
